check the coils my 98 had a crack coil that drove me nuts. If thats the problem make sure you replace both ignition coils

I would check the codes first, with OBDII systems the codes will give you a good idea of what my be doing it, the ETS off is your Electronic Traction-control System, either you have the emergency brake pulled up or it is a seperate issue,
things that may cause your symptoms are,
bad fuel pump-check fuel pressure,
bad MAPS-running the codes should show you if it is but you can also do a diagnostic test
misfire-same as the MAPS, codes will let you know which cylinder then it would be a matter of replacing spark plug and wire(I can't stress enough on getting high quality plugs and wires), if that does not fix the misfire then a compression test is in order
bad coil pack(s)-misfires on two cylinders that are on the same pack, sorry but I do not remember which cylinders are fired by which pack but if you follow the plug wires over to the pack you will see,
vacuum leak-hard to identify but may also have something to do with your ETS light, check the booster vacuum hose for cracks
bad IAC-again the codes should tell you but they may not,
there is the points that I would start off with, I hope that I have been helpful
